' SPACING GAUGE FOR SEWING MACHINES Filed Oct. 19, 1942 Patented June 27, 1944 UNITED STATES PATENT OFFICE SPAGING GAUGE FOR SEWING MACHINES Hyman Rappaport, Bronx, Y. I Application October 19, 1942, Serial No. 463,462:

3 Claims. (Cl. 112-453) and overhanging the edge portion of material being sewn on said sewing machine. A feature of the new spacing gauge resides in the fact that it may easily be adjusted to guide the material being sewn,'as desired.

The invention contemplates numerous modified constructions of the-spacing gauge, which are for the purpose of conveniences in using the gauge. In one form of the invention it is proposed to offset the head portion relative to the stem portion. In another form of the invention it is proposed to provide a clamping screw for engaging against the edge portion of the material being sewn to assist in the guiding operation.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure Fig. 1 is a side elevational view of a sewing machine provided with a spacing gauge constructed in accordance with this invention.

Fig. 3 is a perspective view of the gauge shown in Figs. 1 and 2.

Fig'. 4 is a perspective view of a spacing gauge constructed in accordance with a modified form of this invention.

The spacing gauge for sewing machines, in accordance with the former the invention illustrated in Figs-1 3 inclusive, includes a body Ill having a stem portion I! with a slot l2 for a clamp screw l3-on the bed Id of a sewing machine I5. This machine I5 is shown provided with the usual pressure foot l6 and needle IT. The body is also provided with an upwardly and outwardly overhanging head portion I8 for engaging the edge I9 and overhanging the edge portion 26 of the material 2i being sewn in said sewing machine l5, i v

The body I!) preferably is constructed of sheet metal. The upwardly and outwardly overhanging head portion Iii-comprises a vertical side wall portion 22 which continue's from the stem portion 1 l and which continues into ahorizontal top wall portion 23; The v ertical side wall portion 22 engages against the edge ill for guiding the material 2|. The toowall portion 23 extends over the edge portion 26' of the material 21 to hold it down.

The head portion I8 is set slightly forwards of the stem portion I 0 giving room for the pressure foot 16 and needle I! of the sewing machine. A clamp screw 24 threadedly engages through the top wall portion 23. This clamp screw 24 has a top knurled head 24* and a soft curved bottom head 2 which adjustably engages against the top face of the edge portion 20 of the fabric 2|, being sewn. Instead of the curved bottom head 24*-, a transverse bar 24 isshown to be provided in Fig. 9. a

In Fig. 4 a modified form of the invention has been disclosed which distinguishes from the prior form merely in the design of the parts. This spacing gauge includes a body 25 having a stem portion 26 formed with a slot 21 for the clamp screw l3. One end of the stem portion 26 is'provided with a head portion 28 forming the head of a T-shape in conjunction with the stem portion 26. .An upwardly and outwardly overhanging head portion 29 continues from the head 28. This head portion 29 com-prises a vertical side wall 30 which continues into a narrow shown in Fig. 4, distinguishing in the face that the horizontal top wall 3| is slightly longer and is provided with a prong 33 stamped therefrom and bent downwardly. A clamp screw 34 threadedly engages through the prong 33. This clamp screw 34 has a top knurled knob 35 by which it may be turned. It is also provided with a bottom head 36 which engages against the top face of the edge portion 20 of the fabric 2|, being sewn.

Means is provided for limiting downward flexing of the prong 33 due to its inherent resiliency. This means includes a strand 31 attached to the front end of the prong 33 and engaged through a small cut in the. top of a guiding lug 38 stamped from the material of the wall portion 3!. This lug 38 extends obliquely upwards. The strand 31 continues and is connected with a stud 39 which is slidably mounted in a bayonet slot 40 formed in the wall portion 3|. This bayonet slot 40 has a longitudinally extending portion 4| and several laterally extending branches 42. The stud 39 may be moved from one branch 42 to another branch 42 for letting out or drawing in the strand 3'! which will correspondingly let While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming with the scope of the invention as defined I in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by United States Letter Patent is:

1. A spacing gauge for sewing machines, comprising a body having a stem portion with a slot for a clamp screw from the bed of a sewing machine, and an upwardly and outwardly overhanging head portion for engaging the edge and over-- hanging the edge portion of material being sewn on said sewing machine, said head portion comprising a vertical side wall and a, horizontal top wall, said side wall continuing from said stem portion and said top wall continuing from said side wall portion, and a prong stamped from said top wall, a, clamp screw threadedly engaged through said prong, and means for limiting downward flexing of said prong.

2. A spacing gauge for sewing machines, comprising a body having a stem portion with a slot for a clamp screw from the bed of a sewing machine, and an upwardl and outwardly overhanging head portion for engaging the edge and overhanging the edge portion of material being sewn on said sewing machine, said head portion comprising a vertical side wall and a horizontal top wall, said side wall continuing from said stem portion and said top wall continuing from said side wall portion, and a prong stamped from said top wall, a clamp screw threadedly engagedthrough said prong, and means for limiting downward flexing of said prong, comprising a strand attached to the free end of the prong and guided upwards, and means for holdin said strand in various drawn positions.

3. A spacing gauge for sewing machines, comprising a body having a stem portion for attachment to the bed of a sewing machine and a head portion comprising a vertical side wall for engaging the edge of a piece of cloth being sewn on said machine and continuing into a horizontal top wall overhanging the edge portion of said piece of cloth, a downwardly extending prong stamped from said top wall, a clamp screw threadedly engaged through said prong to bear against the cloth passing beneath said top wall, a stud engaging a bayonet slot formed in said top wall to be movable from one branch to the other of said bayonet slot, and a strand connecting the free end of said prong with said stud for lifting and lowering said prong as said stud is moved along the length of said bayonet slot.
